What kind of memory modules include registers between the system's memory controller and the module's memory chips, registers that communicate in series with the memory controller and in parallel with the memory chips, easing the electrical strain on the memory controller?

A) Double-sided

B) Dual-channel

C) Parity checking

D) Buffered


D) Buffered

Buffered, or registered memory modules (RDIMMs), include specialized chips that act as buffers for all signals from the memory controller, except, in some cases, the data signals. By buffering these signals, the electrical load placed on the controller is reduced because the memory controller communicates in series with the register, instead of in parallel with the memory chips.

Parity checking is a rudimentary error-checking scheme that offers no error correction. It works most often on a byte, or 8 bits, of data.

Double-sided memory allows more memory to be inserted into a computer, using half the physical space of single-sided memory, which requires no switching by the memory controller.

Dual-channel memory is the memory controller's coordination of two memory banks to work as a synchronized set during communication with the CPU, doubling the specified system bus width from the memory's perspective.
